High range resolution at reduced sampling rates in OFDM systems exploiting pilot aliasing
(2024)
High range resolution (HRR) is critical for automotive radar where it is directly dependent on the available transmission bandwidth. However, HRR sensing for OFDM entails high sampling frequencies, which extends the system's ...
Pairwise sequency index modulation with OTSM for green and robust single-carrier communications
(2024)
In this letter, inspired by the fundamental thoughts of sequency index modulation (SeIM) and orthogonal time sequency multiplexing (OTSM), a novel technique is introduced for green and robust single-carrier communications ...
Adaptive handover control parameters over voronoi-based 5G networks
(2024)
Various speed scenarios such as high-speed travelling trains and connected drones over ultra-dense heterogeneous networks (HetNets) may result in a large number of handovers (HOs), which may cause further mobility challenges. ...
Physical layer security using chaotic antenna arrays in point-to-point wireless communications
(2024)
Chaotic antenna array (CAA)s are phased antenna arrays in which individual elements are randomized in their array position, shape, and feed line length. These randomizations generate spatially dependent large scale phase ...
Non-cooperative high-efficiency multi-user ranging using OFDM signals
(2024)
Joint radar and communication (JRC) is attracting increasing interest due to the finite nature of the electromagnetic spectrum and the importance of spatial positioning in modern communications networks. Focusing on the ...
Centralized and decentralized ml-enabled integrated terrestrial and non-terrestrial networks
(2023)
Non-terrestrial networks (NTNs) are a critical enabler of the persistent connectivity vision of sixth-generation networks, as they can service areas where terrestrial infrastructure falls short. However, the integration ...
Enablers for efficient wi-fi sensing
(2023)
Wireless fidelity (Wi-Fi) technology gained popularity due to its ability to provide reliable connectivity, enabling high-speed communication and information sharing. However, in recent years, the focus has shifted from ...
Deep multi-task learning-based simultaneous channel tap and coefficient estimation
(2023)
Wireless communication systems depend on accurate channel estimation to ensure efficient and reliable data transmission. The channel estimation process consists of two essential steps: channel tap and coefficient estimation. ...
